tcp: update the netstamp_needed counter when cloning sockets
[ Upstream commit 704da560c0a0120d8869187f511491a00951a1d3 ] This fixes a netstamp_needed accounting issue when the listen socket has SO_TIMESTAMP set: s = socket(AF_INET, SOCK_STREAM, 0); setsockopt(s, SOL_SOCKET, SO_TIMESTAMP, 1); -> netstamp_needed = 1 bind(s, ...); listen(s, ...); s2 = accept(s, ...); -> netstamp_needed = 1 close(s2); -> netstamp_needed = 0 close(s); -> netstamp_needed = -1 Signed-off-by: Octavian Purdila <opurdila@ixiacom.com> Signed-off-by: David S.
